TRACK CONSTRUCTION. p

Application filed October 22, 1921. Serial No. 509,4707

To @ZZ ila/wm t may concern.'

Be it known that I, JOHN ROBERTS, a citizen of the United States,residing at Elmira, in the county of Chemung and State of New York, haveinvented new and useful v.linerovements in r1irack Constructions of l 3which the following is a. specilication.

My present invention has reference toa railroad track construction.

My primary object is to. produce a novel means for supporting the railsof a track without the employment of spikes or analogous devices and inwhich therails may be properly adjusted with respect to each other sothat either a wide or narrow gauge track may be provided.

A further object is to produce, in a track construction, metal tieshaving adjustably se cured' thereon longitudinally arranged casingsarranged in spaced pairs, each of said casings having movabletherethrough a bolt or key member designed to be brought into wedgingengagement with the base flanges of the rails and locked in suchengagement, whereby the rails will be prevented from tilting or verticalmovement, the construction being such however,l as to permit of thenecessary longitudinal movement of the rails incident to expansion andcontraction.

The foregoing, and other objects which will appear as the nature of theinvention is better understood, may be accomplished by a construction,combination and' operative association of parts such as is disclosed bythe drawings which accompany and form part of this specification.

In the drawings Figure l is a plan view of the main and side lines of arailway track in which the rails thereof are supported on ties inaccordance with this invention.

Figure 2 is a sectional view upon agreatly enlarged scale andapproximately on the line 2--2 of Figure 1.

Figure 3 is a sectional view, also on an enlarged scale, andapproximately on the line 3-3 of Figure 1.

Figure 4 is a perspective view of one of the ties.

Figure 5 is a similar view of another form of tie.

Figure 6 is a perspective view of one of the lock casmgs.

Figure 7 is a similar view of the bolt or key slidable through thecasing.

Figure 8 is a sectional view on the line' 8 8 of Figure l.

As disclosed in Figure 1 of the drawings, the ties'l vary in length ascertain of the ties support thereon the rails of both the main line andthe siding; However, in each instance the ties are constructed of metal,and except when the ties are employed on bridge or trestle works, thesame are cen-- trally formed with a depending longitudinally extendingcentrally arranged rib 2. The fiat ties are indicated by the numeral 3and are bolted, spiked, or otherwise secured' to the trestle works,while the ribs 2 of the ties 1 are embedded in the road bed. rlhus theribs will hold the ties against tilting, sinking or longitudinalmovement. If desired. the ties, at the ends thereof may be provided withopenings through which may pass spikes 4 which enter the road bed andassist'in holding the ties from moving longitudinally.

All of the ties are provided at a suitable distance inward from theiredges and at suitable distances from their ends with longitudinallyextending slots 5. These slots are arranged in spaced aligned pairs neareach end of the ties, and the space between the pairs of slotsapproximately equals the width of the base flanges 6 of the rails 7.Over the pairs of slots on each of the ties there are arranged fiat baseportions 8 of casings 9. The base portions 8 of the casings have boltopenings therethrough land bolts 10 pass through the slots 5 in the tieand through thel said openings in the base portions, the said boltsbeing engaged by nuts 11 whichin turn contact with and press against theupper faces of the base portions of the casings and split spring washers12. The casings 9 are thus capable of sliding movement on the tiesapproximately the length of the slots when the nuts are loosened on thebolts 10. A bolt 13 is mounted in the casing 9 and has a threaded holetherein adapted to register with an opening in the top of the casing toreceive a screw or bolt 15 atv kkio

by actuating those skilled to maintain the'bolt iny position within thecasing. Each bolt or key has its inner or confronting end beveled as at14: to correspond to the angular cross sectional contour of the upperportion of the base flanges of the rails; v

It. is believed that the foregoing description,v when taken in'yconnection with the draw-ings will amply set forth the construction andadvantages ofy the improvement to in the art to which thisinventionrelates, it being understood that the slots inv the ties permit ofalongitudinal movement of the lock casings thereover so that the tiesmay be employed for supporting the rails of either a narrow or widegauge track. It will be also understood that the locking means for thebolt.,

to unlocking position, the bolts or keys may be moved through thecasings out o'l' rail en-l gagement, and while I have illustrated anddescribed thesaid embodiment of the Vimprovement as it now appears tome, it is to be understood that I am not to bey restricted.`

to the Idetails of construction herein referred to and illustrated, butam entitled to such departures therefrom as fall Within' the scope ofwhat is claimed. v l

Having described the invention what is claimed is 1. In combination withatie plate having spaced slots therein,'a casing havingoutwardlyextending base flanges mounted over the slots, a bolt mountedinthe-casing adapted to engage a track rail, and means securing saidcasing to the tie through the slots therein. l 2. In combination with atie plate having a pair of spaced parallel slots at each rend, a casingincluding a hollow central portion and base members extending from saidcern tral portion, said base members being d'is posed over the yslots intheties, a bolt mounted in the casing for engagement with a track rail,and means mountedfthrough saidslots f and base members slidablyconnecting the casing with the tie. l

In testimony whereof I aiiix my signature.

JOHN ROBERTS.
